The original spline on the left has very few, unevenly distributed points. An identical spline has been placed as a child of a mtSplineSample on the right. This has been resampled using 150 points in the Uniform mode. The result is a smooth, higher-quality spline.
You have three options: Uniform, Natural and Distance.
The default setting, the Method is Uniform, distributing a uniform amount of points per segment.
An INSYDIUM logo spline is on the left. On the right, a duplicate spline has been made a child of a mtSplineSample, using the Uniform Method.
